i have posted a few questions regarding having issues about getting no power to my fuel pump!?! Is it possible that my key may be faulty and the car isn't reading the key thus not sending power to the pump in order for the car start, or also something to do with the anti-theft system?? Does any one know if this is what happens if the car doesen't read the signal from the key? (not send power supply to the fuel pump). have changed pump, checked all relays + fuses also everything else electrical is working!!!!

 

If the car doesn't read the signal from the key, the immoblizer system would be activated causing a light (car with an x through it) to flash on the dash and no start. I know from experience! Tech remembers

As always, if I'm wrong, correct me tech!

 

yes you are right, looked it up in the manual. With me switching relays around and getting them to work again has sent power to the pump but the car is still not starting., I have replied to your other post explaining that i had to get a diagnostics test done and tghe reading was faulty camshaft sensor so i will keep you posted on the outcome whenever i get my new one ok ,thanks v. much...

 

Ya, I know! Stupid Volvo charged me mucho dolores to fix that immobilizer!
